IMPROVEMENT IN WATER-EJECTORS.

Specification forming part of Letters PatentNo. 49,603, dated August 29,1865.

To all whom it may concern:

Be it known that I, N. L. GHAPPELL, ot' the city, county, and State ofNew York, have invented certain new and useful Improvements in Ejectorsfor Discharging Bilge-Water, and for other purposes, ot1 which thefollowing is a full, clear, and eXact description, reference being hadtothe accompanying drawing,which i'orms a part of this specicatiou, andwhich represents a vertical section ot' an ejector constructed on my newand improved plan.

Ejectors as constructed heretofore have been very defective, as therewas no provision made in their construction for the removal ofobstructions in the induction-pipe. When the induction-pipe becameobstructed the ejector had to be removed for the purpose of cleaning itor for removing the obstructions, thereby causing considerable labor andloss ot' time.

The object of this invention is to make a simple and eli'ectiveprovision l'or the removal ot' obstructions from the induction-pipewhile the ejector remains in its position.

I will now describe the construction anal operation of an ejectorconstructed on my new and improved plan,with reference to the drawing.

A is a round hollow globe with four openings, ot' which B is theinductioirport and C is the ed uctioirport. These ports B and C are inline with an axis passing through the center ol" the globe A. ln alineat right angles to B and@ are two openings, D and E, in the sides of thehollow globe A. Into the openings D and E a steam-shaft, F, is fitted insuch a manner that it canrevolve, and by means of stuffing-boxes H H andproper packing the said fittings at,D and E are made air and watertight, for the purpose of preventing the air from being drawn in betweenthe steam-shalt and the bearings of the globe A, and also for thepurpose ot' preventing leakage of water, both of which would beinjurious to the operation of the ejector.

The steam-shaft F is made hollow from one end to about one-halt o1" thelength thereof, and near the point where the solid and hollow parts meetis provided with a steam-nozzle, G, which is fitted and screwed into thehollow part in line with the eduction-port G.

I is a lever or handle attached to the solid end of the steam-shaft F,by means ot' which the action of the ejector is changed or reversed.

A steam-pipe is connected with the hollow end of the steam-shaft F bymeans of properfaced couplings, sothat the said shaft can be turned orreversed. The induction-port B is connected by any well-known means to apipe through which the water and other matter is to be drawn into theejector, and the eductonport C is connected with another pipe throughwhich the water and other matter is to be ejected.

When the nozzle G is placed with its port toward the port C of theglobe, and steam or compressed air is admitted at the outer hollow endinto the steamshaft F,as the steam or air issues through the nozzle G itwill cause the water or other matter to enter at the port B and bedischarged through the port G and the pipe connected therewith.

Should the induction pipe B become obstructed, then it will be simplynecessary to reverse the steam-shalt F so as to bring the nozzle G inline with the port B, and as the steam passes through the port B and thepipe attached thereto it will force any obstructions out of the pipe.

The ejector may be used for filling tanks or other vessels with water,in which case it must be provided with another induction and anothereduction port, which may be located on the sides of the globe A. Theaction of the ejector in such case will be substantially the same asbefore mentioned-that is to say,whcn the nozzle G is turned toward theport which leads to the tank, and the steam is made to pass through thesaid nozzle into the pipe which leads to the tank, then the water willenter at the induction-port and will be ejected through the eductionport and pipe into the tank or any other vessel by the force ot' thesteam.

Compressed air may beusedinstead of steam in this ejector, and theejector may be used for other liquids than water.

/Vhat I claim as my improvement, and desire to secure by Letters Patent,is-

The removable or reversible shaft F, having an attached nozzle, G, oroutlet, in combina tion with an ejector, substantially as and for thepurpose herein specied.
